Apologies to recent cachers. The cache has now been updated (6/9/2020). The cache is an ammo box, old and painted camo. It is placed high enough to be above the river's high-water levels (I hope!) The original was a hollowed out section of log with the L&L in it, but I failed to consider how quickly untreated wood would degrade. Given that a boat is needed to get to this, I decided I did not need to make it any harder, so the placement is not disguised and while I could not avoid some thorns completely, it is easier to approach than in the past.
This is a very pleasant section of the river, that doesn't require any white-water skills, along the back side of the Bartholomew's Cobble Reservation, with a good chance of spotting a heron or two. The Cobble is worth a visit while you are here. http://www.thetrustees.org/places-to-visit/berkshires/bartholomews-cobble.html The very adventurous could also approach the cache from the dam at Falls Village, CT, but it would be a long paddle (15 miles round-trip) with one very short bit of white water at an old, failed dam. This is about 5.25 miles north of the boat launch at Falls Village, and can be portaged. I've paddled it down-river in a kayak, but have never tried to paddle upstream. You would need experience and the right boat.
One warning: if you approach the island from up stream, there is an inviting 'landing' spot - a small channel just big enough for a canoe or two. Unfortunatley, the mud/silt is knee deep, so you may want to land elsewhere.
